CUSHION-EDGE SUPPORT.

To all lwhom it may concern:

Be it known that I, FRANK H. HAMPTON, a citizen of the United States ont America, and a resident of Pullman, county'of Cook, State of Illinois, have invented certain new and useful Improvements in Cushion-Edge Supports, of which the following is a speclficatio l The main objects 'of this invention are to provide an improved form of edge-pad for supporting the edges of seat cushions so that they will permanently retain their original shape, and to'provide an improved form of holder for securing such edge-pads to the edges of spring structures and bracing the pads against lateral distortion. These objects are accomplished by the device shown in the accompanying drawings, in which-` Figure 1 is al top plan, partly broken away, of a spring-supported cushion frame provided with. cushion-edge supporting means constructed according to this invention. Fig. 2 is a transverse section of the v edge-pad retainin holder or retaining iframe by means of which the edge-pad is held in position upon the spring structure. Fi 34 is a transverse section of the casing o the pad. lFig. L is a sectional view corresponding to Fig. 2, but showing the edge-pad in position in Y, the holder, and showing the holder in its relation to the sprinr structure.

In the form shown in the drawings, the spring structure or main trame 1 has an trame mounted on its u per surface an comprising a plurality o holders 2 arranged in succession so as to extend around the edges of the top of the frame 1. Each ot the holders 2 is formed ot a strip of sheet metal bent upon itself so as to' ave a uniform transverse section substantially of the shape illustrated in lFig. 2 and comprising a dat plate adapted to be attached to the upper surface ot the spring structure and having a double channeled groove extending along its outer edge. 'Ihe outer channel 3 ot the groove serves as a seat for the edge-pad, and the inner channel 4 serves as a seat for the retainin bead, the web which connects the pad an bead extending throu h the slot 5. The holder 2 is preferably o such form that it will rest flat upon the upper surface oit the spring structure, as shown in Fig. a.

In the form shown, the ed e-pad consists ot a casing ozt Horrible materlal, preferably fabric such as canvas, lled with a stuiling which will give the desiredstiil'ness to the pad. This stuing is usually sawdust, which tends to preserve the shape of the edges of the cushion and at theV same time yields to the proper degree under the weight of the occu ant. The casing of the pad'is preferably ormed by looping or folding a strip of canvas lengthwise in opposite directlons along two arallel lines and securing the layers toget er by a line of stitching running lengthwise between the folds. Thus are formed two parallel tubular casings 6 and 7 the casin 6 being vpreferably considerably larger than the casing 7. One line of stitching at 8 is all that is necessary for forming the casing, and the free edges 9 and l() of the strip form Aconvenient aprons to which the lining of the cushion may be attaehed without perforating the casing, as

would be the case if said linings were sewed i directly to the casing 6 of thel pad 11. "Ihe pad 11 is formed by lilling the casing 6 with a core of suitable stuiiin material, as hereinbefore mentioned; an the retaining bead is formed by inserting a core 12 into the casing 7. The core 12 1s preferably of more rigid material, as, for instance, a fiat strip of meta-l.

The channel 4c of the groove is preferably of iiattened crosssection, so that it will occupy a minimum amount of Vspace and allow the pad l1 to be made as large as possible. rIhe side walls 14 and l5 of the channel 3 are so formed as to properly seat the pad 11 and at the same time support it against lateral distortion.

The holders 2 are preferably spaced apart at their adjacent edges so that they can yield to a certain extent independently oit each other under unequally distributed loads. By making the holders 2 comparatively short, they may be made of comparatively light- Inetal without danger ot becoming per manently distorted when a load is concen trated at a small area near the edge of the cushion.

Adjacent holders are .so arranged that their grooves are substantially in alinement with each other, so that the pad 11 may be made in one continuous strip and be drawn successively through the holders until its ends abut at some art of the periphery ot the cushion. 'Ihe a utting ends may then be sewed together so that the pad will be practically endless. When the pad is in vposition on the frame, the aprons 9 and 10 extend over the edges of the walls 14 and 15.- The cushion proper may be made of anyl said padand seated within said inner channel for retaining the pad in the groove.

2. The comblnation of a cushion frame having a surface 'for supporting adding material, an ed e-pad extending a ong the edge ofv said surface and projecting outward therefrom, a seat for said ed e-pad, and walls projecting from said sur ace at both sides of said edge-pad to brace said edgepad against lateral distortion.

3. A cushion-edge support, com rising a strip of sheet .metal bent upon itself to form a double channeled groove comprising an outer channel and `an inner channel connected by a contracted slot, an edge-supporting pad seated in said outer channel and extending outward therefrom, and a bead seated in said inner channel and connected with said pad for retaining it in position.

4. The combination of a spring structure havin a surface for supporting padding material, a plurality of holders, each having therein a groove comprising an outer channel and an inner channel connected by a contracted slot, said holders being arranged along the edge of said surface with their grooves in substantial alinement, a continuous edge-pad extending along and seated in the outer channels of the grooves in said holders, and a bead connected to said pad and seated in the inner channels of said grooves for retaining said pad.

5. The combination of a spring structure havin a surface for sup orting padding material, a plurality'of hol ers, each having therein a groove comprising an outer channel and an inner channel connected by a contracted slot, said holders being arranged along the edge of said surface with their grooves in substantial alinement, a continuous edge-pad extending along and seated in the outer channels of the grooves in said holders, and a lbead connected to said pad and seated in the inner channels of said .grooves for retaining said pad, said holders being s aced apart to permit relative movement ue to the yielding of said spring structure.

6. In a cushion-edge support, the' combination of a frame having a groove extending along the edge thereof, said groove comprising an inner channel opening through a contracted slot; and an edge-pad comprising a strip of flexible material looped upon itselfto form parallel tubular casings, cores insaid casings, one of said casings, together with its core fitting within said groove for securing sai pad to said frame, and an apron extending along said pad and adapted to 'permit the cushion -lining to be sewed thereto without perforating the casing of the edge-pad.

7. In a cushion-edge support, the combination of a frame havin a groove extending along the edge thereo said roove cornprising an inner channel openlng through a contracted slot; and an edge-pad comprising a strip of flexible material looped upon itself to form parallel tubular casings, cores in said casings, one of said casings, together with its core, fitting within said groove for. securing said pad to said frame, the edges of said strip extending -a considerable distance at each side of said cascushion lining.

8. The combination of a cushion frame havin a surface for supportin padding material, padding material distri uted over said surface, an.ed e-pad extending along the edge of said sur ace and projecting outward therefrom, and comparatively rigid means projecting from said surface at both sides of said edge-pad for bracing the edgepad against lateral distortion.

9. The combination of a cushion frame, an edge-pad disposed along thel edge of said frame, and a plurality of sheet metal holders arranged about the edge of said frame 'and extending outward therefrom .at both sides of said edge-pad 'to brace it against lateral distortion.
